We successfully completed an upgrade project going from AIX 4.3.0 to 5.2 and IDS 7.30 to 7.31 (application vendor did not want 9.40!). On top of that, we introduced HDR into the mix. The "upgrade project" also included new hardware though (went from an F50 to two B80's in an HDR replicated pair). We had enough time and single point of responsibility (us) to plan and provide everything, including extensive testing, and we had a good, successful project. If you are going towards an in-place upgrade (i.e. you do not have a separate server you can at least test this with) on both AIX and IDS, then I would recommend upgrade one at a time (actually I would recommend go ahead and buy a cheap box you can use for testing this if you do not have one)...
